Sound is loud and clear
Let me tell yall, I purchased the 20 inches for my 2019 polaris slingshot inclousers sub boxes, and these things are the bomb dignity, I mean I love them the bass hit is deep and bold, I get lots of compliments on the way they sounds. So guys go out and get a pair and you want be disappointed
The Pro CF 6x9 is a well built beautifully looking and sounding speaker! Very happy with DS18 and the product they sell!
Thank you DS18!
i love them i got them to complete my 6 speaker rack and now everyone looks at me when driving
This amp has been nothing short of amazing. I have it powering the DS18 shallow mount 10 and it’s very powerful.

Shetty horns my stunt wall better with QF and JN bc i like to hop on trends
I heard quinns setup with these while i was cruising in my clapped out corolla and now i cant hear out of my left ear
The DS18 PRO-DKH4 is absolutely worth it if you’re chasing serious volume, clarity, and pro-audio level performance. This driver uses a massive 4-inch titanium voice coil and a heavy-duty bolt-on horn that delivers extremely loud, crisp highs without breaking a sweat. With high sensitivity and real power-handling capability, it cuts through road noise, crowds, and outdoor environments effortlessly. The build quality is on another level — the materials and weight alone show it’s made for competition setups, big systems, and anyone who needs their mids and highs to stay clean even at extreme volumes. It’s not meant for casual stock upgrades or soft, warm sound; this is a driver built for people who want aggressive, high-output vocals and instruments that project like a concert speaker. If your system is designed for loud, clean performance and you want a top-tier horn driver that can keep up with big amps and big bass, the PRO-DKH4 is worth every dollar.
made ears bleed bought 5 of them for my churro
These scream, must buy never buying another horn.
I thought my Walmart tweeters was crisp until I ordered these they took my sound to another level
if you are having someone install this for you its the best you can get for this price. im very very happy with the product.
however i was thinking the install would be a lot more plug and play as far as mounting the door speakers and tweeters. other than that no issues at all
